Description

[Detailed description of the invention] This invention relates to a powder sorting device for various spreaders such as fertilizers and seeding machines, and is designed to distribute powder such as fertilizer from the discharge port of a hopper to the left and right and spread it. At the same time, the left and right distribution ratio of the powder and granular material can be adjusted arbitrarily.The feature is that there are two hoppers with chevron-shaped boundaries below the discharge opening of the hopper. In a powder or granule sorting device for a spreader equipped with a funnel having a flow path, in order to adjust the ratio of the amount of powder or granule distributed to the two flow paths, the boundary part is set relative to the center of the discharge port. The main advantage is that the lateral position can be adjusted freely.

Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments.
In the figure, 1 is the tractor body, 2 is the rear axle case, and 3 is the tractor body.
4 is a rear wheel, and 4 is a rotary device, which is attached to the tractor body 1 via a three-point linkage mechanism 5 so as to be movable up and down.

6 is a fertilizer applicator as an example of a spreader, and a hopper 7
The rear axle case 2 is attached to the rear axle case 2 via the mounting member 8.
is supported by

At the lower end of the hopper 7, as shown in FIGS. 2 and 3, a stirring chamber housing 9 and a feeding chamber housing 10 are provided. Room cabinet 1
A feeding shaft 14 having a feeding roll 13 is rotatably inserted in each of the rollers 0 .

The stirring shaft 12 and the feeding shaft 14 are interlocked with each other, and are also interlocked with a drive wheel 16 at the tip of the chain case 15, and are driven by the lug of the rear wheel 3 in synchronization with the vehicle speed.

The feeding roll 13 has a plurality of feeding recesses 17 at equal intervals in the circumferential direction, which fit into an outer cylinder 19 having a cutout 18 formed from one end in the axial direction, and the open side of the cutout 18. An inner cylinder 21 having a protrusion 20 and fitting into the outer cylinder 19
The outer cylinder 19 can be freely adjusted in the axial direction from the outside of the dispensing chamber casing 10 via an adjustment shaft 22, and by adjusting this, the volume of the dispensing recess 17 can be changed to adjust the dispensing amount. is adjustable.

The adjustment shaft 22 can be fixed to a pin hole 23 by a pin 24 which can be inserted into and removed from the pin hole 23 .

Reference numeral 25 denotes a funnel disposed below the discharge port 26 of the dispensing chamber housing 10, and as shown in FIGS.
7, and two channels 28 divided into left and right by this
, 29, and the funnel 25 is supported by a guide piece 31 formed by bending the front and rear edges of a support plate 30 so as to be slidable in the lateral direction.

The support plate 30 is for supporting the funnel 25 as described above, and is supported by a pair of left and right mounting members 32 so as to fit around the discharge port 26 .

The mounting member 32 is provided vertically from both sides of the feeding chamber casing 10, and an adjustment bolt 33 for regulating the lateral position of the funnel 25 is screwed into the lower end of the mounting member 32 in a forward/backward direction.

34 is a lock nut, and 35 and 36 are pipes connected to flow paths 28 and 29.

Next, the action will be explained.

When driving with the drive shaft 16 in contact with the rear wheels 3, the stirring shaft 12 and the feeding shaft 14 rotate in the direction of the arrow in synchronization with the vehicle speed of the tractor, and the fertilizer in the stirring chamber housing 9 is stirred by the stirring rod 11. At the same time, the stirred fertilizer is fed out in fixed amounts by a feeding roll 13.

In this case, the amount of feed by the feed roll 13 is determined by the adjustment shaft 22.
This is done by sliding it in the axial direction.

That is, when the adjustment shaft 22 is slid in the axial direction, the outer cylinder 19 integrated therewith slides, and the length of the feeding recess 17 formed by the outer cylinder 19 and the inner cylinder 21 changes. It is possible to arbitrarily adjust the amount of feed.

The fertilizer fed out by the feeding roll 13 is transferred to the feeding chamber case 1.
Fertilizer falls into the funnel 25 from the discharge port 26 at the lower end, is divided into two channels 28 and 29 by the chevron boundary 27, and is applied to the field from the pipes 35 and 36.

In this case, since the feed roll 13 is configured to adjust the feed amount by sliding the outer cylinder 19, the feed recess 1
There is a problem in that the position of one end of the discharge port 7 changes, making it impossible to determine the delivery position.Furthermore, when working on a slope in the contour line direction, the tractor body 1 tilts left and right.
It may fall to one side from 6.

Therefore, in such a case, taking into consideration the effective width of the dispensing recess 17 of the dispensing roll 13, the inclination angle of the tractor body 1, etc., the chevron boundary section 27 directs the fertilizer falling from the discharge port 26 to each of the left and right channels. The funnel 25 can be adjusted in the lateral direction in order to evenly distribute the ingredients to 28 and 29, and this adjustment is performed using the left and right adjustment bolts 33.

In other words, since the funnel 25 is supported by the guide piece 31 of the support plate 30 so as to be slidable in the lateral direction, if each adjustment belt 33 is rotated in the opposite direction, the funnel 25 can be moved in the lateral direction along the guide piece 31. This causes the chevron boundary part 2
7 in the lateral direction with respect to the center of the discharge port 26, the distribution ratio of the fertilizer distributed to the two flow paths 2B and 29 is adjusted, and the deviation of the feeding recess 17 or the tractor body 1 is adjusted. The distribution ratios, which had large differences due to the inclination, are adjusted to be approximately the same.

As described above, according to the present invention, in the powder or granule sorting device for a spreader in which a funnel having two flow paths with a chevron-shaped boundary is disposed below the discharge port of the hopper, the two flow paths are arranged. In order to adjust the ratio of the amount of powder and granular material distributed to the flow path, the position of the boundary part can be adjusted in the lateral direction relative to the center of the discharge port, so by adjusting the position of the boundary part in the lateral direction, the two It is possible to adjust the distribution ratio to the flow channels, and the amount of powder and granules sprinkled from each flow channel can be adjusted, which changes the delivery position above the discharge port. or when the position of the lower boundary changes due to the inclination of the spreader, and there is a difference in the distribution ratio to the two flow paths due to the boundary, the distribution ratio can be made equal. It is possible to modify it back.
